法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for manufacturing plated steel wire from rolled wire rod, and more specifically, the present invention relates to an improvement in a method for manufacturing plated steel wire from rolled wire rod, and more specifically, the present invention relates to an improvement in a method for manufacturing plated steel wire from rolled wire rod. This invention relates to a method that facilitates surface cleaning and simultaneously improves productivity.
圧延した線材からメッキ鋼線を製造する場合、その製造
工程は圧延線材からスケールを除去して冷間引抜し鋼線
にする過程と、鋼線にメッキを施してメッキ鋼線を得る
過程の２つの段階に大別できる。When manufacturing plated steel wire from rolled wire, the manufacturing process involves two processes: removing scale from the rolled wire to make cold-drawn steel wire, and plating the steel wire to obtain plated steel wire. It can be roughly divided into two stages.
ここで前者の冷間引抜きにより鋼線を製造するまでの過
程について述べると、従来は圧延線材を酸洗して表面の
スケールを剥離させ水洗を行い、次いで石灰石けん液を
塗布し乾燥したのち冷間引抜きを行うのが一般的であっ
た。Here, we will discuss the process of manufacturing steel wire by cold drawing. Conventionally, rolled wire rods are pickled to remove scale on the surface and washed with water, then coated with lime soap solution, dried, and then cooled. It was common to perform thinning.
これを分り易く図示すると次のようになる。This can be illustrated in an easy-to-understand manner as follows.
ところで、最近では公害および作業環境上の問題から酸
洗によるスケール除去に替って機械的にスケールを除去
する方法が増加しつつある。Incidentally, recently, mechanical scale removal methods have been increasingly used instead of pickling scale removal due to pollution and work environment problems.
これを図示すると次のようになる。This is illustrated as follows.
このようにして製造された鋼線は次にメッキ用前処理を
施されたのちメッキ浴槽に導入されメッキ鋼線となる。The steel wire manufactured in this manner is then subjected to a pretreatment for plating, and then introduced into a plating bath to become a plated steel wire.
メッキ鋼線の製造過程については種々の方法があるが、
処理の高速化、無公害化を計った新しい方法として、無
酸洗ガス還元方式による鋼線の連続溶融、メッキ方法を
先に特願昭５０−９６０１６号として出願した。There are various methods for producing plated steel wire.
As a new method aimed at speeding up the process and making it pollution-free, we have previously applied for a method for continuous melting and plating of steel wire using a non-pickling gas reduction method as Japanese Patent Application No. 1983-96016.
この新しい方法を用いてメッキ鋼線を製造するにあたり
、前述図示した従来の伸線過程において製造された被メ
ツキ鋼線を使用した場合、残存スケール、潤滑剤、防錆

るには、還元炉における還元性ガスの還元力を高めるか
、ガス量を増すか、還元時間を増す必要が生じてきた。When manufacturing plated steel wire using this new method, when using plated steel wire manufactured in the conventional wire drawing process shown in the diagram above, the amount of residual scale, lubricant, rust preventive, etc. on the surface will be reduced. Therefore, in order to improve productivity and quality, it has become necessary to increase the reducing power of the reducing gas in the reduction furnace, increase the amount of gas, or increase the reduction time.
また被メツキ鋼線の表面に付着した潤滑剤、防錆剤など
を除去する前焼きおよびワイピングによる前処理を強化
しなければならなくなってきた。In addition, it has become necessary to strengthen pretreatment by pre-baking and wiping to remove lubricants, rust preventives, etc. adhering to the surface of the steel wire to be plated.
これらの問題を解決するには、設備設置スペースの拡大
を必要とし、処理コスト増大による経済性の低下を考慮
しなければならないし、また処理技術の面でもより高度
なものが要求されるなど、生産効果を高めるにあたり多
ぐの障害が発生してきた。In order to solve these problems, it is necessary to expand the equipment installation space, it is necessary to consider the decline in economic efficiency due to increased processing costs, and more advanced processing technology is required. Many obstacles have arisen in increasing production efficiency.
したがって、従来の鋼線の製造過程を改良し、残存スケ
ール、潤滑剤、防錆剤などの異物の付着の非常に少ない
鋼線を製造しメッキ処理過程に供給することが強く要望
されるに至った。Therefore, there is a strong demand to improve the conventional steel wire manufacturing process, to produce steel wire with very little adhesion of foreign substances such as residual scale, lubricants, and rust preventive agents, and to supply it to the plating process. Ta.
本発明はこのような情勢に基きなされたもので、従来の
鋼績製造過程を改良し、さらに改良された新しい方法に

ったことを特徴とする圧延線材からメッキ鋼線を得るま
での一貫したメッキ鋼線の製造方法を提案することを目
的とする。The present invention was made based on the above situation, and is a continuous plated steel wire using a non-pickling gas reduction method, which is a method of manufacturing plated steel wire by improving the conventional steel manufacturing process and using a new and improved method. The purpose of this invention is to propose a method for manufacturing plated steel wire that is consistent from rolling wire to obtaining plated steel wire, which is characterized by supplying the material during the manufacturing process to improve productivity and quality.
このため、本発明では鋼線製造工程中のスケール除去を

圧水噴射により洗浄し残存スケールをより完全に除去し
、スケールが殆んどないが故に冷間引抜きに際して濃度
が薄く少ない潤滑剤で済むようにして異物の付着の少な
い鋼線を製造する。For this reason, in the present invention, scale is removed mechanically during the steel wire manufacturing process, and the surface of the wire after scale removal is washed with high-pressure water jet to more completely remove remaining scale, resulting in almost no scale. Therefore, a steel wire with less adhesion of foreign matter can be produced by requiring less concentrated lubricant during cold drawing.
さらに、このようにして冷間引抜した鋼線を冷間ワイピ
ングを施すことにより線表面より完全に異物を除去した
のち無酸洗ガス還元方式によるメッキ鋼線製造過程に供
給するようにした。Further, the cold-drawn steel wire was subjected to cold wiping to completely remove foreign matter from the wire surface, and then supplied to the plated steel wire manufacturing process using the non-pickling gas reduction method.
本発明により、表面に付着物が少ない状態でメッキ用前
処理が施せるようになり、還元時に還元ガス量や還元時
間を増加させるような操作は不要となった。According to the present invention, pretreatment for plating can be performed with less deposits on the surface, and operations that increase the amount of reducing gas or the reduction time during reduction are no longer necessary.
そして、作業の安定性と生産性の向上が計れると同時に
、メッキ鋼線を得るまでの全工程で酸を使用せず作業環
境の向上を達成できるようになった。This not only improves work stability and productivity, but also improves the work environment by eliminating the use of acid in all processes up to producing plated steel wire.

する。The entire manufacturing process of the present invention consists of the step (B) of first applying the rolled wire rod to a bending roll to peel off the scale on the surface, and then removing the remaining scale by contacting it with solid grains or by brushing it. Pressure 50kg/c
A step of cleaning with high-pressure water jetting of m2 to 200 kg/cm2 (C) A pretreatment step of applying a rust preventive/lubricant and drying, and then ■) Cold drawing the steel wire to be plated. And the steel wire obtained in this way is (

a step of annealing and reducing within a range of 850°C and then cooling;
((3) Steps of plating by immersion in a molten metal bath, adjusting the amount of plating deposited using a squeezing device, and then cooling) will be described in detail with reference to the drawings.
第１図において、巻枠１から出た熱間圧延後の線材２は
、ベンディングロール３に掛けられ表面のスケールが剥
離される。In FIG. 1, a hot-rolled wire 2 coming out of a winding frame 1 is passed through a bending roll 3 to remove scale from the surface.
ベンディング吊−ルは線材に曲げ加工を繰り返し与えな
がら表面のスケールを剥離させるが、この段階ではスケ
ールを完全に除くことはできない。The bending hanger repeatedly bends the wire material to remove scale from the surface, but the scale cannot be completely removed at this stage.
次いで線材２は、固体粒充填箱４に送られ残存スケール
が除かれる。The wire rod 2 is then sent to a solid particle filling box 4 to remove residual scale.
線材を固体粒充填箱に通すかわりにショツトブラストを
かけたり、ブラッシングを行ってもよい。Instead of passing the wire through a box filled with solid particles, it may be shot blasted or brushed.
ところで、ベンディングロールや固体粒との接触により
線材のスケールはあらかた除去されるが、それでもなお
線材表面に未剥離のスケールやスケール粉が残っている
のが現状である。Incidentally, although most of the scale on the wire rod is removed by contact with bending rolls or solid particles, the current situation is that unpeeled scale and scale powder still remain on the surface of the wire rod.
特に最近では生産性向上の面から処理線速を早める傾向
が強く、約５０〜３００ ｍ／ｍｉｎの速度で作業が行
なわれる。Particularly in recent years, there has been a strong tendency to increase the processing line speed in order to improve productivity, and work is carried out at a speed of about 50 to 300 m/min.
したがって線材表面に残留したスケールが後述する石灰

石灰石けんの劣化を早めたりスケールで汚れた石灰石け

を阻害したりダイズの消耗を増大させたりする原因とな
る。Therefore, there is a risk that the scale remaining on the surface of the wire may be carried into the tank of anti-corrosion and lubricating liquid such as lime soap, which will be described later.
Wire rods coated with lime soap that are contaminated with lime soap and lime soap accelerate the deterioration of the lime soap, which impairs wire drawability during cold drawing and increases consumption of soybean.
したがって本発明では防錆・潤滑剤を線材に塗布する前
に、線材表面に付着するスケールを完全に除去するよう
にした。Therefore, in the present invention, scale adhering to the surface of the wire is completely removed before applying the rust preventive/lubricant agent to the wire.
すなわち、前述の固体粒充填箱４を出た線材２は、高圧

替も少なくてすみ、さらに線材の仕上りも非常に美しく
なった。In addition, the lime soap tank was no longer dirty, the lime soap had to be replaced less frequently, and the finish of the wire became much more beautiful.
種々のテストの結果、水噴射の圧力は５０ｋｇ／ｆｆ１
以上でないと目的を達成することができないことが判明
した。As a result of various tests, the water injection pressure was 50kg/ff1
It became clear that the objective could not be achieved without the above.

で乾燥して巻取枠８に巻取る。The wire rod 2 that has been cleaned by high-pressure water jet is then rust-proofed and
It is sent to a lubricant liquid tank 6, where it is coated with an appropriate amount of lime soap etc. to improve the wire drawability during cold drawing, and is then sent to a drying device 7.
The film is dried and wound onto a winding frame 8.
その後、巻取枠８の線材２は冷間引抜機９で所定の減面
率で伸線され巻取枠１０に巻き取られてメッキに適した
鋼線となる。Thereafter, the wire rod 2 of the winding frame 8 is drawn at a predetermined area reduction rate in a cold drawing machine 9 and wound around the winding frame 10 to become a steel wire suitable for plating.
なお、乾燥装置７からの線材２は一旦巻取枠８に巻取る
のが普通であルカ、乾燥装置７と冷間引抜機９を連接さ
せ巻取枠８を省略してもよい。Incidentally, the wire rod 2 from the drying device 7 is normally wound up on the winding frame 8, but the drying device 7 and the cold drawing machine 9 may be connected and the winding frame 8 may be omitted.
このようにして冷間引抜きした鋼線２は、メッキ処理用

その前に冷間ワイパー装置１１で冷間ワイピングを行な
うよう）こした。The steel wire 2 cold-drawn in this way is supplied to a reduction process for plating treatment, but in the present invention, before that, it is particularly cold-wiped with a cold wiper device 11). .
これは適切な伸線を高速で行うには前述した石灰石けん
塗布段階で一定濃度の石灰石けんや潤滑剤を塗布してお
く必要があり、冷間引抜き後の鋼線にこれらが幾分か付
着しているからである。This is because in order to properly draw wire at high speed, it is necessary to apply a certain concentration of lime soap and lubricant at the lime soap application step mentioned above, and some of these adhere to the steel wire after cold drawing. This is because they are doing so.
もし、これらの異物が付着していると、還元工程前の前
焼やワイピングを強化しなければならないことになる。If these foreign substances are attached, it will be necessary to strengthen the pre-baking and wiping before the reduction process.
冷間ワイパー装置１１としては、高速回転ブラッシング

冷間ワイピングを施し清浄になった鋼線２は無酸化加熱
炉１２で加熱し、還元炉１３でガス還元しながらメッキ
槽温度まで冷却する。The steel wire 2 that has been cleaned by cold wiping is heated in a non-oxidizing heating furnace 12 and cooled to the plating bath temperature while being gas-reduced in a reducing furnace 13.
加熱炉１２は鉛浴炉またはガス焚炉が使用される。As the heating furnace 12, a lead bath furnace or a gas firing furnace is used.
